JOHN PRESTON, OF INDIANAPOLIS, INDIANA.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 270,983, dated January 23, 18 3. Application filed December 5, 1882. (No model.)

To all whom at may concern Be it known that I, JOHN PRESTON, of the city of Indianapolis, county of Marion, and

State of Indiana, have invented certain new and useful Improvements in Horse-Powers, of which the following is a specification.

The object of my said invention is to produce a horse-power of simple and inexpensive construction, and which shall occupy less space than the ordinary horse-power. This object is accomplished by combining as the essential working mechanism of the machine three shafts, connected by gears, two of which shall be at substantially right angles with the other, as: will be hereinafter more fully described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a perspective view of a horsepower embodying my invention; Fig. 2, a side elevation of the same, showing the opposite side to that shown in Fig. 1; Fig.3, ahorizontal sectional view, as seen when looking upwardly from the dotted line 2 z in Fig. 2.

I n said drawings, the portions marked Arcpresent the frame-work of the horsepower; B, the ordinary power-shaft or tumbling-rod, 0, an intermediate or speed shaft, and D the master-wheel or driving-shaft.

The frame-work A consists simply of a stout bench-like frame or bridgetree mounted on a bed-plate, A, which in turn is preferably mounted on a platform, as shown.

The tumbling-shaft B is mounted in a bearing, b, on the bed-plate A, and bears upon its inner end the bevel-pinion B, which engages with the bevel-wheel O by which it is driven.

The intermediate shaft, 0, is preferably set vertically at right angles with the tumblingshaft B. It bears the bevel-gear wheel 0, which engages with and drives the pinion B, and the spur-pinion G which engages with the master-wheel. The relation of this pinion to the master-wheel is shown by dotted lines in Fig. 3. This shaft O is mounted in a step, a, on the bed-plate A, and in a bearing, a, on the frame-work A. V

The shaft D is mounted in a step, d, on the bed-plate A, and in a bearing,d,on the framework A, and is also steadied in position by the brace d which is connected to said shaft by wheel D, which drives the pinion O and thus I the shaft O and gear-wheel O, and through said gear-wheel the pinion Band the tumblingshaft B, which is attached to the machine to be driven.

This power is intended for light work, such as sawing wood, cutting feed, and such other work as can be done on a farm where the power required is not more than that of a single animal, and where, therefore, the ordinary large horse-power cannot be used economically.

The small size and simple construction of this horse-power render it inexpensive, and it can thus be afforded in many places where the old and more expensive devices would be unprofitable.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a horse-power, of the frame-work, the shafts B, O, and D, the wheels B, 0, G and D, and the lever D, substantially as set forth.

2. The combination, in a horsepower, of an internally-toothed mastcr-wheel,a pinion with which the same engages, a bevel-gear wheel on the same shaft as said pinion, and a powershaft or tumbling-rod having a pinion thereon with which said wheel engages, substantially as set forth.

3. A horse-power the mechanism whereof consists essentially of three shafts connected by gears, two of said shafts being at substantially right angles with the other, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 2d day of December, A. D. 1882.

. JOHN PRESTON.
